Function Code Parameter Name Setting Range Default
F1-28 Encoder type
0: ABZ incremental encoder
1: UVW incremental encoder
2: Resolver
3: SIN/COS encoder
4: Wire-saving UVW encoder
0
The MD380 supports multiple types of encoder. Different PG cards are required for different
types of encoder. Select the appropriate PG card for the encoder used. Any of the five
encoder types is applicable to synchronous motor. Only ABZ incremental encoder and
resolver are applicable to asynchronous motor.
After installation of the PG card is complete, set this parameter properly based on the actual
condition. Otherwise, the AC drive cannot run properly.
Function Code Parameter Name Setting Range Default
F1-30
A/B phase sequence of ABZ
incremental encoder
0: Forward
1: Reserve
0
This parameter is valid only for ABZ incremental encoder (F1-28 = 0) and is used to set the
A/B phase sequence of the ABZ incremental encoder.
It is valid for both asynchronous motor and synchronous motor. The A/B phase sequence
can be obtained through "Asynchronous motor complete auto-tuning" or "Synchronous
motor no-load auto-tuning".
Function Code Parameter Name Setting Range Default
F1-31 Encoder installation angle
0.0°–359.9° 0.0°
This parameter is applicable only to synchronous motor. It is valid for ABZ incremental
encoder, UVW incremental encoder, resolver and wire-saving UVW encoder, but invalid for
SIN/COS encoder.
It can be obtained through synchronous motor no-load auto-turning or with-load auto-tuning.
After installation of the synchronous motor is complete, the value of this parameter must be
obtained by motor auto-tuning. Otherwise, the motor cannot run properly.
Function Code Parameter Name Setting Range Default
F1-32
U, V, W phase sequence of UVW
encoder
0: Forward
1: Reverse
0
F1-33 UVW encoder angle offset
0.0°–359.9° 0.0°
These two parameters are valid only when the UVW encoder is applied to a synchronous
motor. They can be obtained by synchronous motor no-load auto-tuning or with-load auto-
tuning. After installation of the synchronous motor is complete, the values of these two
parameters must be obtained by motor auto-tuning. Otherwise, the motor cannot run
properly.
